( I've posted this in a few different forums trying to cast a wider net.)

I have a 2019MY Vantage.  After 3 1/2 years, 7000miles and kept in a garage, the ignition coils and plugs corroded.  See pic below.




I am posting to find out if others have had a similar issue with their V8 cars.

(I had the Timeless Warranty and Aston gave me a terrible hassle about covering the repair.  Even though the repair was ultimately covered, only due to the efforts of the dealer, Aston corporate aggravated me so much that I will never buy another Aston product. My view of the Timeless Warranty being “ultra-luxury”toilet paper will be for a post on another day.)

The damage was caused by water getting into the engine bay and sitting on an area of the engine that doesn’t drain properly.  The dealer couldn’t find out how the water got in. They refit the cowl, checked the drains…everything fine.  They said they have seen this problem before but I didn’t get specifics ( I know the v12 DB11 has had issues and is apparently unresolved but I am specifically focused on the AMG V8 Unit) . Considering how many miles are typically put on these cars and the favorable conditions they are driven in, that is not a great endorsement.

Obviously given some cars have vents, this is not a completely sealed area. It seems like, as many places where water can get into an area of a car, it should be designed to drain if it gets wet. Apparently that is not so for this specific engine installation.

Since it was never determined exactly how it happened, I have little confidence that it won’t happen again.  I asked why this wasn’t evaporated by the heat of the engine, worst case, and this was unknown.

To make a long story short, I’m trying to find other owners that have had the same issue.  From everything I can tell, this is either the fault of the design or a poor installation. We all know( well except for Aston Martin) that coils and plugs are not a maintenance item after 7000 miles.  I’m confident there was nothing singularly peculiar about my car. If this happened to me it will happen to others.
I’m posting this on a few sites to get as many owners as I can. Please let me know if you have had this problem as I am keeping data.

I am trying to get an idea of just how widespread this problem is.  In the meantime be forewarned about driving your car in the rain.  rolleyes

Wow after 7k that is shocking. Most cars eg ferraris etc have a seal that covers the spark plug recess so that water does not go there. Looks like they have maybe missed something in assembly.
I hope it is not common to all VV8's or that they have provided a solution.

So where the coil packs sit is under the black covers or carbon covers on each side.

Looking at an m177 spark plug change then there is a little bit of a valley on each side.

Obviously the cover has holes in, I don't think the merc versions beyond the air box on each side has any covers or the aston one has any covers below the black plastic or carbon one.

I suspect they are working on use and engine temperature to remove any water hanging round. But there is a big but, the M177 is known to have the odd issue with coil packs, I don't want to say the two are linked without proof.

I might have a nose at mine if possible, without removing the covers, using a borescope.

Also having a nose at the M177 C63 forums it is interesting to mention an updated coil pack. The original on the left and updated on the right.



Note the accordin section, is this to stop water getting near the spark and misfires? A little bit of me says yes, next question is are Aston also using the updated coil pack, an answer I don't know.

That info about the C63 is good info to know. Sure looks like the same type of issue to me. I knew this couldn’t be some freak accident.

I think the Vantage engine is an M178. I’ll have to check if the coils are the same for both the m177 and m178 and see if any changes were made.

Aston gave me a terrible time about covering this under the Timeless Warranty. To the point where I would never buy another Aston product. ( I’ll write about that hassle sometime later.). For two weeks they denied the claim. After a couple weeks I told the shop I would pay for the repair out of my pocket and I started prepping to sue Aston after it was fixed and I got my car back. ( That’s how I ended up with the photos and such as I was gathering the info.)

At the eleventh hour, the dealer told me there was no charge for the repair. It was getting nasty. The dealer never told me there was a redesign for the Aston coil. I’ll have to contact them and see if the Aston coil has a newer revision like the m177 coil.

Ah ha, Ninja 59 has shown that there clearly is a problem and that is why they have installed a re designed coil pack with a rubber inbuilt seal. I would suggest it should be a recall issue and should be rectified under this recall.

It will be good to see what happens next if a group of new vantage owners join forces as this seems a pretty basic design problem. Is the replacement of coil packs on the amg engine as hard to do as that on a pre amg v12?

I don’t know if it is as difficult as some other cars but I will tell you that the estimate for the job was about $5k from the dealer. Sounded outrageous to me but that is what I was quoted when I authorized the repair. Never saw the final itemized invoice when I picked up the car because it was eventually covered.

From conversations throughout the process. Over $1500 for coil packs, about $493 for plugs and they said it was 5 or 6 hours labor…I think labor rate is $239/hr.. no doubt a huge Aston tax in my area. Not sure how they got to $5k.

( Annual Service with oil change is about $1800. ( maybe that includes a brake flush, don’t remember.). Oil change alone is $1k. Only brought it to the dealer because it was under warranty. Not sure if there are any Aston independents in my area so next oil change will be DIY.)

M177 is our engine as it is wet sump, but the sump is unique to AM. M178 is dry sump and the AMG GT only.

The AM sump is from my knowledge all metal, unlike the merc version, downside is oil level sensor on the AM sump can cause at least for me the odd issue with false levels due to my garage position.

We don't know if merc during build will have fitted them, so it is a little wide sweeping to say all will have had the earlier design, the car in question was 2017, so an early c63 w205.

On the v8 it is black covers off remove all the wiring with a few bolts, 3 bolts for each coil and it is out. There is a fuel line in the way of one which from what I have heard just needs moving.

OP was yours a 2019?

My car is a MY19 shipped to Canada originally.

It appears the coils for the M177 c63s and the M178 AMG GT are the same.( I mention this because I think Aston calls this the M178 engine regardless of the modified/alternative sump. I’m guessing there are multiple subvariants of the M178. I’m just trying to get the best apples to apples information.)

I fired off an email to my dealer to find out if the newly installed coils had the updated rings along the boot. They never mentioned that there was a part update. Given how ticked off I was about this not being covered they may not have wanted to confirm my belief this was caused by a poor design and not some freak issue. Of course, Mercedes could have updated the part and Aston could still be using the original part for some reason. I haven’t heard back from the dealer yet.

As I mentioned this car had the Aston Martin Timeless Warranty for which I paid about $4000 USD for an additional year. Undoubtedly expensive and I expected it to be comprehensive. I was shocked when Aston denied the claim saying it was caused by “water ingress” and not covered. Aston was complete A-holes about it. At one point, they said “ as a courtesy, they would cover 60% of the costs”. I paid 100% of a warranty and wasn’t settling for a 60% payout under any circumstances on something I saw as either a manufacturing defect or a faulty installation. At one point, they even claimed it wasn’t really an Aston Warranty because it was “ administered” by a third party and they had no control over it. Every word out of the mouth of the Aston rep was foolishness. When I asked to speak to his supervisor, he claimed he didn’t have one. I asked who he reported to and he said no one. “Everybody had quit!” What a joker. Clearly the inmates are running the asylum.

I called a few US numbers for Aston. All of them either went to general voicemails or were covered by a company called Morley who claim they are just hired to answer the phone and relay messages in the US for Aston. Anyway, I digress and the warranty shenanigans will be taken up later.

For now, I’m just tracking down if this was a freak one off issue or if others have experienced it. It’s looking like it’s a known issue. Plan to swing by the Mercedes service department at some point soon for a chat.

I’m not letting this one go. I think Aston were pretty shabby in their treatment of this issue.

$1000 for an oil change.... that is highway robbery. Oil say $150, filters say $100 labor 1.5 hrs at $150ph total $475 max. I find it a bit less of a wallet hit by buying my own oil about a month before the service and Filters via Aston Bits so all I pay for is the labor at the service interval.

I think we need to super careful here did AML Gaydon deny the claim or did it get denied by the region or did (like I suspect) it get denied by a 3rd party (as at least in the UK) a number of even on the face manufacturer specific warranties are not actually underwritten by the manufacturer, but a 3rd party.

After two weeks of getting nowhere with the claim, the dealer had me contact the AML representative directly.

( I think I'm not allowed to give specific names and phone numbers on here so for now I won't)

I don't remember the specific title of the person I spoke to at AML but I do have his name. He said he was a regional rep. He said he had no supervisor and didn't report to anybody else. I did try to call the "After Sales Manager, Aston Martin of the Americas" but that person ( who I happened to have the cell phone contact from last year) had apparently resigned just a few days previously and no other person returned the call in his place. I left a message with the main operator ( Morley) for the "new" After Sales Manager" ( unknown name at this point) and got no call back. I then left two messages for the President of Aston Martin, Americas and got no call back. ( Given the revolving door at Aston, I'm not even sue who the current president is. I called the one who was appointed a few months back, LOL)

The regional rep said he had no say with the claim. He said the Timeless Warranty was NOT actually an Aston Martin product and the claim was denied by a third party. When I asked him the name and number of the third party he then said he didn't have that info and could not supply it to me. So, essentially, according to Aston, AML rep is the interface to the administrator and I can't speak with them myself. Aston rep is the gatekeeper. If I have an issue, take it up with....nobody. It was all very vague and unconvincing. It was a classic runaround.

The Aston rep said it was being denied because it was " water ingress" and the contract doesn't cover "water ingress" ( My interpretation of the catchall term "water ingress" refers more to flooding and deep puddles in the context which it is used in the contract. Very different than poor design of the ignition coils, manufacturing defect or faulty installation)

He said, "as a courtesy, and we are being generous, we will offer 60% coverage". I said I don't need your generosity, I need you to do the right thing and pay the claim. I bought a warranty that was represented as an Aston Martin product, from an Aston Martin dealer and was sold as comprehensive. I paid 100% for the warranty and I expect 100% payment. I said instead of hassling your customers, you should be talking to the person who is denying the claim and tell them this should be covered. He thought that was funny.

So from the best I can tell, the claim was denied by Aston Martin Lagonda of North America. I don't know if it ever made it to Gaydon. When I told my servicing dealer and my local sales rep that AML claimed that the Timeless Warranty/Extended Service Contract was a "third party product", they all found that to be a bit of a head scratcher. The Aston dealer interacts directly to Aston corporate, not a third party intermediary. The dealer does not deal with the administrator either.

This is the only sponsored, and marketed product Aston sells in the US. The "Provider" is "Aston Martin Lagonda of North America" ( The number to reach customer service, which doesn't get answered is Aston Martin in Irvine, CA) There is a an "Administrator", called "Care Care North America". This number also goes directly to voicemail and no return calls. An email to Car Care also went unanswered. As an interesting note, the "Car Care" number for the Administrator on the Aston Website is incorrect, having only six digits and it needs seven in the US. When I looked up the corporate records for Car Care, the people listed were all based in the UK, although the phone number is a Florida number, for what that is worth.

( The Extended Service Contract itself lists "Warrantech" as the "Administrator", but the website and rep I spoke to said it was "Car Care". I don't know or care who these entities are because my Extended Service Contract is made with the "Company" in the document. In the 28 page contract, the term "Company" refers to "Aston Martin Lagonda of North America, Inc."

Anyway, this is "The" Aston Martin warranty we all think about when getting the best protection, regardless of how Aston has structured it. It is the one advertised all over Aston's website and the one sold by Aston dealers in North America. It is clear to me that Aston corporate has ultimate control over this product.

The Timeless warranty is a 3rd party warranty. In my view Iit is mis sold as you buy it from an Aston Dealer and it has Aston all over it. If the 3rd party company refuses the claim, the AM dealer may help, but legally don't have to.
Been there, got the T shirt. No help from the dealer

I did hear back from the servicing dealer. Aston does have a new part number for the coils and the new Aston coils have the three ribs.

Not sure why I wasn't informed of this when the repair was made and I picked up the car. I did query why this happened and why it won't happen again but was never told that the part was redesigned. They searched for how the water got in and never found a culprit. Maybe the service advisor didn't know about the part redesign until I brought it to his attention. Maybe they didn't want to admit that there really was a design issue rather than this being some freak accident given how livid I was about Aston denying this as a warranty repair.

So the good news is I have a bit more faith this won't happen in the future. I guess we'll see if the new design does a better job. The bad news is Aston knew this was a design fault with the car and I think it was rather unfortunate they refused to cover the claim for weeks. So much for this being the "ultra-luxury" brand Stroll tries to portray. In my experience, higher end brands go above and beyond trying to rectify a problem. It left such a bad impression regarding Aston customer service that I will never buy another Aston product. Well, I'm off to my test drive an Arturo in a couple days.. Aston who?

Thanks again to @Ninja59 for pointing me in the right direction.

Ah hah! I should have suspected. "Warrantech" are the biggest pieces of sh*t going. Good luck with anything going forward. I had a Volvo with their "coverage" what a total scam.

In honesty they might not have even known until the part arrivedas part numbers end and begin regularly. I think they should have informed you have the design change, but then tbh that is likely to be at a tech level to service adviser issue.

Plus this issue was an merc level issue, so it might have been even less apparent.

The way to cut past that crap is asking to speak to the workshop foreman or tech that worked on the car. They will get miffed but I have found previously it helps avoid missing problems or how things are resolved.

Regarding water getting there then water will always in some way enter at some level into the engine bay the critical bit is where it lands and how items are protected from the elements.

The ignition coil cover does have holes in, so when you put all that together then it is obvious it needs to be protected. Even the original version features a wider section, so I suspect mercedes knew it needed protection, but the original measures were not enough.

To add to this having done 700 miles in mine in the past few days then the bay has no apparent water entry although most of the journey was dry. I suspect the heat of the engine avoids most of the issues.

I am now aware however of one GT mercedes that ended up with a bent conrod due to water entry via the spark plug...

For those that wish to get just the rubber section I now note there is two options the entire coil pack and rubber section or just the rubber section on astonmartinbits! The rubber section is £50 each, where as the coil packs are £712 each.
